The springs i) are so disposed that beforeone leaves the indicate correprojection on the rings (t the nor springtouches thereon, as shown in Fig. 6, which is essentia for the properworking of the machine. During each revolution of the shaft theprojections will form contact with the entire series of springssuccessively. The cxciting-cnrrcnt is transmitted from the rntiini. s'irings by connecting wire roiis ii to the eicoire-magnets U. The wirerods (Z tines. through the blocks Z) from one ring-ironic A? to theother interineiiiately between anti parallel. to the magnets U, as shownin Fig. 3. The enrrent-,in entering; through anyoneot the "ntiinlsprings I), is ilit'iiled, as shown in i and passes from the rod d inopposite direction through the coils of all the electro-inognets (3,being nniteii again on the tliinnetriezilly-oppo site rod and retnrneiithrough the opposite spring and contact-ring to the source of sup ply.The result ofthis disposition of the current is that all theeicctro-ningnots etone iii-l6 of the springs; will receive on oppositepolarity to the remaining magnets on the other side of these springs.

The center magnet may also be used by connectingthe same with a source of electricity, as the inducing part, andgenerate currents in the outer magnets, using them as the armature-herethe inducing-magnet would be the moving part while the armatureis atrest-Jeavin g the whole construction as before, a steady current wouldflow through the helices, springs, center rings, and so on. By closingthe circuit of each ouler electro-magnet separately I obtain alternatecurrents in each magnet, which currents can be employed for theproduction of electric lights requiring alternating currents.

In using the machine as an electro-mo'tor,

the revolving armature as well as the exterior electro-magnets areexcited bythe same or separate currents. The action of the outer magnetshaving the same polarity as the armature will repel the latter, whilethe magnets of opposite polarity will attract the same, andv therevolving armature, following the result-ants of all these attractionsand repulsions,will move toward the poles of opposite polarities. in sodoing it will bring the next set of springs in contact with theprojections of the suppl y-rin gs, continuing the rotary motion andcausing the center shaft to revolve with a power proportioned to thestrength of the current applied and to the sizeof the cores used.

It is obvious that thema'chine can also be used by interchanging theconstruction of the v outer magnets with the inner magnets.

The electro-magnts may be made hollow and either a current of air orwater passed through the same, so as to keep them cool, if

desired.

in place of the segmentalcores of the armature, a cylinder formed ofpermanentsteel mag netswhose poles of equal name would have to face thesame way may be used.

The advantages of this construction are that by presenting the outer andinner magnets in their full length parallel to each other a largerpercentage of induced currents is obtained. The currents, instead ofbeing composed at a sum or succession of currents, as in the presentwell-known types of magneto-electric machines, will be of unbrokencontinuity while the inducing action upon the armature takes place. Bymaking the eccentricity relatively small the entire motion of attractionand repulsion, as also induction, occur within the im mediateneighborhood of the acting poles where the lines of force are mostdense, and as magnetic and electrioforces diminish in an inverse ratioof the sqnare of the distance, it is self-evident that while theleverage will decrease in a direct algebraic ratio the power willincrease in proportion of the square thereof, showing a clear gain inmaking the eccentricity as small as practicable. By inserting apole-changer of any appropriate construction into the circuit I canreverse the polarity of the current and magnets, and in this way reversethe inotiou of the motor, for instance.

A further advantage is 'thatmagnets provided with intermediate poleswill not retain any residual magnetism thcmoment the exciting-currentceases.

Havingthus described myinvention,I claim as new and desire to securebyLettcrs Patent- 1. In a magneto-electric machine, the com-' binationof fixed outer electro -inagnets, an eccentric armature, springs b andf, revolving rings and cams, substantially as described.

In a magneto-electric machine, the co n bination of a main shaftadapted to receive a laterally-adjustable eccentric armature, mech-.fixed exterior electro-inagnets arranged in a circle with intermediateisolated blocks, radial springs attached thereto, and conducting-rodswhich pass through said blocks, in combination with alaterally-adjustable revolving armature, a main shalt which carries aneccentric and an eccentric armature which revolve within the circle ofthe magnets, con tact-pieces, contact-rings, and came attached to saidshaft, which transmitthecurrentto theradialsprings, substantially asdescribed.
